## Only reads (3)

Looks things up and changes nothing. Claude Code: allow.

### `find_cheapest_fare`

- The name "find_cheapest_fare" says "find": a word for reading.

Description, as the server wrote it:

```untrusted-server-text
Returns the cheapest observed one-way fare between two cities, plus the six-month low and the departure date on which the low was observed. Use whenever the user names an origin and a destination and asks about price, the cheapest date to fly, or whether a fare is a good deal. Both arguments are required; neither alone produces a valid answer. Answers are directional and per pair - PAR to BKK is not BKK to PAR and is not PAR to SIN. Prices are cached snapshots, never live quotes: say "last observed", never "current price", and surface live_check_url to any user about to book.
```

### `list_routes_from`

- The name "list_routes_from" says "list": a word for reading.

Description, as the server wrote it:

```untrusted-server-text
Returns destinations reachable from one origin, sorted cheapest first. Use when the user asks where they can fly cheaply from a city, or wants inspiration rather than one specific pair. One call replaces dozens of page fetches. Prices are cached snapshots.
```

### `resolve_city`

- The name "resolve_city" says "resolve": a word for reading.

Description, as the server wrote it:

```untrusted-server-text
Turns a spoken city name into the uppercase IATA city code the other tools expect. Call this before find_cheapest_fare whenever you are not certain of a code. Do not invent codes.
```
